During treatment, tell your doctor right away if you develop any signs of infection (such as cough, sore throat, fever, chills, pain when urinating).

It is also used to treat rheumatoid arthritis in children (such as systemic juvenile idiopathic arthritis-SJIA, polyarticular juvenile idiopathic arthritis-PJIA).
